HENRY ROBERTS, OF PITTSBURG, PENNSYLVANIA.

METAL-COATING APPARATUS.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed January 7, 1909. Serial No. $71,069.

To all'whom it may concern:

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a cer- 1 tain new anduseful Improvement in Metal- Coatmg Apparatus, of which the following isa full, clear, and exact description, reference being had to theaccompanyingdrawings,

- forming part of this specification.

The object of my invention is to providein metal coating apparatuswherein the metal after being subjected to a cleaningtoripre paratorytreatment is caused to be passed;

. through a molten bath of coating material,

. side elevation; and Fig. 4 is a fragmentary the tension adjustmentscrews 8'.

sectional view of a wiping roller to beherein after referred to.

I shall now describe my invention so that others skilled in the art towhich it appertains may understanr' and construct the same.

In the drawings, the reference numeral 2 indicates the coating bath of ametal coating mechanism. Journaled in the bearings 3 and 4, slid ablymounted in the ways 5 of the framework 5 overhanging that end of thebath 2 from which the coated metal emerges, are the rollers 6 and 7. Theroller 7 is sur faced with a wiping material against which the movingcoated metal is adapted to be forced by means of the roller 6 throu hthe medium of coiled springs 8, provide with By means of the pinarrangement 9 the bearings 4 of the roller 7 may be held againstmovement in the ways 5 of the frame 5, while also a1- lowing of theready removal of the rollerfor the insertion of another roller when thewipguished from a brush which .will leave a I more or less unevensurface. I prefer, however, to use mineral wool, as asbestos, as I Ifind this to be admirable wiping material by reason of the fact that itdoes not adhere to the melted coating metal. In Fig. 4 I show the roller7 formed with the peripheral recesses mend around this recessed surfaceI place a layer of mineral wool or asbestos 11, which is bound to thesurface of the roller by means ofthe asbestos rope 1.2. The wipingmaterial applied to the roller in this manner pre- ,sents a surface thatis not easily disintegrated by the abrading action. of the metal duringthe wiping operation, the cushion effect caused by the interposed layerof the material producing an efiective wiping action.

The constructionof th'e wiping roller or 1 rollers may vary according tothe shape or pattern of the metal to be coated; For in stance, in thecase of wire fabric, where con.

nective knots or joints are present, it vfill be apparent that theseknots or joints will have more of an abrading or disintegrating actionon 'the wiping material during the Wiping operation thin the strands orboay por tions of the fabric, in which case it would be desirable toprovide those portions of the or joints contact, with a thicker wipingsurface than would be required for the body of the fabric. Also in thecase of wire strands, only those portions of the rollervadapted toreceive the strands may be provided with wiping material.

The wiping rollers 6 and 7 are adapted to be rotated by any suitablemeans in a direction opposite to that of the moving coated metal whichpasses upwardly from the coating bath to between the rollers 6 and7, asshown in Fig. 1. Any suitable mechanism may be employed for drawing themetal through the coating apparatus.

The advantages of my invention will be appreciated by those skilleel inthe art.

adaptable to the coating of wire fabr'c, the

such as to insurethe contact of the wiping material with every portionof the coated fabric as it emerges from the bath.

While I have shown and described my apparatuses having only one" rollerprovided with wiping material, it will be appa re it that severalrollers may be employed ll deslred. Many other changes will suggestthemselves The invention will be found particularly construction ofthewipingmechanismbeing to. the mechanic which .would not be a departurefrom my invention and I do not therefore desire to limit myself to theprecise construction shown. c

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

I 1. A roll for removing the surplus coating from metal as it emergesfrom a coatingbath, having a covering of suitable wiping -material andfacushioning material between the body of the roll and the Wiping surface.

- wipin surface.

2. A roll for removing the surplus coating from metal as it emerges froma coating bath, having a covering of suitable wiping material and acushioning medium also of wi mg material between the body of the roll anthe roll for removing the surplus coating from metal as it emerges froma coating bath,

hayingja complete covering of wiping mate- 7 ma 4. A roll for removingthe surplus coating a from metal as it emerges from a coatingbath,

having a complete covering comprising a rope or strand of wipingmaterial.

r5. A, roll for removing the surplus coating from metalas itemerges froma coating bath,

. having eripheral recesses, a cushioning medium o wiprngmaterialfilling said recesses and covering the surface of the roll and anexternal covering of wiping material sur rounding and binding saidcushioning medium.

6. A roll for removing the surplus coating from'metal as it emerges froma coating bath,

bearings slidably mounted in said guide Ways, detachable means forretaining said bearin s therein, and a spring" ressed tension ro erhaving bearings slida ly mounted in said gulildeways and cooperatingwith said r0 er.

Wiping 8. p aratus for removlng the surplus I coating rom metal as itemerges from a coating bath comprising a supporting frame provided withguideways, a wiping roller surfaced with wiping material and havingbearings slidably mounted in said guideways, detachable means forretaining said bearings therein, and a spring-pressed tension rollerhaving bearings slidably mounted in-said guideways and cooperatingwith-said wipin roller, said wiping rollerbeing provide with annularflanges adapted to extend beyond the ends of the tension roller.

In testimony whereof, I have hereunto set my hand. I
